Patented Nov. 22, 1910.

Application filed July 14, 1909, Serial No. 507,488. Renewed October 8, 1910. Serial No. 586,067.

To all whom it may concern:

Be it known that I, ALBERT T. MEYER, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Attachment for Scoring-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures and letters of reference marked thereon, which form a part of this specification.

My invention relates to means which is particularly applicable for use on scoring machines or the like and adapted to guide the movement of paper, card board or other material fed thereto to cause it to be cut into a predetermined shape.

The object of my invention is the provision of a simple, and highly efi icient device of this class, which, when thrown into operation, is automatically operative to guide the movement of the material being cut relative to the cutter to cause it to be cut into a predetermined shape, such as a circle, oval or the like.

The operation, construction and arrangement of the parts of the invention are fully described in the following specification, and a preferred embodiment thereof illustrated in the accompanying drawings, in which,

Figure 1 is a front elevation of portions of a scoring machine with my invention associated therewith and adapted for oval or oblong cutting. Fig. 2 is a section of the same, as along the line w m in Fig. 1. Fig. 3 is an enlarged side elevation of the attachment comprising the invention, with a portion of the same in section. Fig. 4 is a front eleva tion of the same. Fig. 5 is a vertical sec tion thereof on the line 1 y in Fig. 3. Fig. 6 is a perspective View of the work engaging part of the attachment which is used when making circular cuts. Fig. 7 is an inverted perspective view of the work engaging part which is used for cutting pieces into oblong shape with circular ends, and Fig. 8 is a bottom view of the pressure-foot.

The attachment constituting my invention is adapted for use on any of the usual forms of scoring machines, such machines comprising in particular a work-supporting shaft or roll 1, the rotary movements of which are controlled in any suitable manner, and a revoluble bar 2 to which the cutters are attached, and which is rocked by hand to throw the cutters into or out of operative position.

This attachment is shown in the present instance as comprising a holder 8, which is clamped in any suitable manner to a rib 4 on the edge of the bar 2, as by a set-screw 5 threading through a part of such holder and cooperating with a hinged plate 6, as shown in Fig. 3, and is provided in its under side with a vertical bore 6 for the stem 7 of the pressure foot 8 to work in.

A screw 9 is threaded into the under side of the foot 8 and its head carries a roller 10, which is peripherally shouldered to adapt it to cooperate with a work-engaging member 11 to hold it in loose revoluble contact with the bottom of such foot. The member 11, when adapted for guiding work to cause it to be cut into oblong shape such for instance as indicated by the line a in Fig. 2, is provided with the oblong opening 6 for receiving the roller 10, the wall of which opening is of equal thickness throughout its length and constitutes the rounded or semi-circular ends 0 and the straight sides cl. The member 11 has its upper inner edge formed with a flange or shoulder e, which fits over the peripheral shoulder of the screw head, as indicated in Fig. 5, and has its upper outer edge formed with a surrounding flange or shoulder f, which works in a complemental groove 12, provided in the inner side of a flange 18 depending from one side of the foot 8. The flange 13 has its inner side straight throughout its length to adapt it to cooperate with the roller 10 to guide the member 11 for transverse movement only relative to the foot when a side (Z of the member is in contact with such flange, thus preventing a turning of the member until an end thereof moves into contact with the roller 10, when it is permitted to make a half turn around such axis to move its other straight side into contact with the flange 13.

In order to prevent a slipping of the member 11 relative to the work when in contact therewith, such member is provided on its lower face with a. plurality of brads 14 for piercing the work.

The lowering and raising movements of the foot 8 are controlled by a lever 15, which projects within a socket 16 provided in the holder 3 in register with the upper end of the bore 6, such lever being pivoted within said socket, as at 17, and having its inner end working within a slot 18 in the upper end of the stem 7. A spring 19 acts on the lever 15 to normally maintain the pressurefoot in elevated position.

If it is desired to cut the work into circular form the member 11 and its holding parts are removed from the foot and a screw or part 20, see Fig. 6, having a pivot-pm 21 projecting from its lower end, is substituted therefor. IVhen lowered in contact with the work the pin 21 permits a circular movement. thereof.

The usual cutting disk 22, which cooperates with the roll 1 to cut the work, is sus pended from the bar 2 by a carrying-arm 23, which is attached to the rib 4 of the bar 2 in any suitable manner to permit adjustment of the cutter longitudinally of the bar.

The operation of the invention is as follows The. cutter-disk 22 having been placed in proper position relative to the holder 3 to cut a blank in the desired size, a blank A is placed between the roll 1 and the disk 22 and pressure-foot S with its central portion disposed under the latter, and the lever 15 is then operated to lower the pressure-foot to cause the bradded face of the member 11 to engage the work. The rotation of the roll 1 being now started the blank is caused to have a circular movement due to the disk 22 holding one side of the same to the roll as it cooperates therewith to cut the blank. The blank, however, instead of having a true circular movement is caused to have straight movements equal to the length of the sides (Z of the member 11, when either of said sides is in contact with the guideflange 13 of the pressure-foot 8, s0 that opposite sides of the blank are severed in straight lines of corresponding length, as indicated at 9, while the end portions of the blank are severed in circular lines with the pivot roller 10 as their axis, which is due to the ends of the member 11 contacting with the roller 10 and describing a half revolution around the same. Should it be desired to cut the blank in a true circle the member 11 and its holding parts are removed from the pressure-foot and the pivot member 21 substituted therefor. v

I wish it understood that my invention is not limited to any specific construction, shape, size or arrangement of the parts except in so far as such limitations are specified in the claims.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent, is,

1. In an apparatus of the class described, the combination with a rotatable shaft, and
